2 Claims.

This invention relates to improvements in a bond tightener and sealer wherein a preferably solid polygonal reel operates in conjunction with a loose latch or bar operatively connected in .spaced parallel relation thereto, to tighten and substantially seal a bond or flexible band embracing a package or cargo to be secured, when the ends of said bond are inserted between said solid reel and loose bar and said reel and bar are rotated to wind thereon any surplus amount of bond and thereby tighten and seal the same.

The primary object of the present invention is to provide a new and improved bond tightener and sealer for securing freight and other objects against movement upon a carrier during rough or tempestuous transportation.

Another object is to provide a new and improved device of the character set forth which subsequently may easily be released and retightened and rescaled during a, rough voyage to take up the slack in a bond caused by jars and jolts.

A further object is to provide a new and improved bond tightener and sealer of the type described which may be used repeatedly without destroying the bond or lashings, so that both tightener and bond may be used indefinitely upon successive cargoes with a saving of time and material.

I accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present application, and in which Fig. 1 is an elevationn of a cargo of bulky packages secured together and to a carrier, and disclosing the application of my improved bond tightener and sealer;

Fig. 2 is a side elevation, on an enlarged scale, partly in section, of my improved tightener and sealer, disclosing the manner in which a bond, in the form of a flexible metallic band or strap embracing a cargo, has its free ends snubbed and sealed, and said band tightened to secure said cargo, after the device has been operated;

Fig. 3 is a front elevation of the device before the flexible band is tightened and sealed;

Fig. 4 is a partly broken plan view of the reel 1 the cargo to the deck of the carrier I, I have provided the bond tightening and sealing device consisting of a preferably solid reel 4, hexagonal through the length thereof for economy of construction as well as efficiency in operation. One side of said reel 4 is provided intermediate the ends thereof with a pair of spaced lateral lugs 6 cupped, recessed or grooved upon their inner or adjacent faces, as at l.

Between these cupped lugs 6 is slidably mounted for limited movement the ends of a solid latch or bar 8 arranged substantially in parallel spaced relation with the axis of the reel 4, as disclosed in Fig. 4 of the drawings.

A detachable wrench 9 is arranged to engage either end of the solid hexagonal reel 4 while a crank l2, having the usual lateral extension or handle I4, is arranged to detachably engage an opposite end, as disclosed in full lines in Fig. 3 of the drawings, whereby said reel 4 may be rotated to snub, wind up and seal the flexible metallic band 3, in a manner and for a purpose hereinafter more fully set forth.

In operation:

A cargo, comprising one or more cases 2 or the like, is placed upon the deck of the carrier I and embraced by the flat flexible metallic band or bond 3. The opposite ends of the band 3 are then inserted from opposite directions between the bar or latch 8 and the reel 4, as indicated in dotted lines in Fig. 2 of the drawings.

Either the wrench 9, crank [2, or both, are moved into engaging relation with opposite ends of the reel 4 and by means of said wrench 9 and crank 12 said reel is rotated, preferably counterclockwise, as indicated by the curved arrow in Fig. 2 of the drawings.

The first half of a revolution of the reel 4 will bend or snub the ends of the band 3 around the bar 8 and reel 4 and take up the slack which previously has been approximately. determined, while another complete revolution will wind said band 3 around the outer side of the bar 8 and tightly press the same onto that portion or those portions of the ends of said band 3 between said bar 8 and reel 4 and the resulting tension of said band 3 will tend to tightly seal and snub the band 3, as fully disclosed in full lines in Fig. 2 of the drawings.

During the tightening process above described, the lateral extension or handle M of the crank I2 is positioned away from the band 3, as indicated in dotted lines in Fig. 3 of the drawings. After the band 3 has been sufficiently tightened, the reel 4 is held against counter rotation by the wrench 9 while the crank I2 is removed and returned into engaging relation with its end of the reel 4 but with its lateral extension or handle l4 reversed or lying within the path of and adjacent to the band 3, as disclosed in full lines in Fig. 3 of the drawings, so that any tendency of the tension of the tightened band 3 to rotate the reel 4 in a counter or releasing direction will be prevented by contact of the extension l4 itself. This locked position is also indicated in full lines in Fig. 2 of the drawings.

It is obvious that the band 3 subsequently may be retightened during a rough or tempestuous voyage, to take up any new slack which may be caused during violent motion of the carrier I. This may be easily and readily accomplished by the simple expedient of attaching the wrench 9 to the reel 4 and rotating the same .sumciently to move the extension M from contact with the,

tape 3. The reel 4 may then be rotated to retighten the band 3 and the crank readjusted to the new position.

It is obvious from the foregoing that not only may a cargo be quickly, easily and effectively secured and sealed to a deck to prevent movement or shifting thereof during a rough voyage, but also that the device easily and quickly may be released, with the proper wrenches or cranks, and used repeatedly, along with the same lashings, bonds or flexible bands, thereby efiecting a considerable saving in lashing material, time and labor.

Having described my invention, I claim:

1. A bond tightener and sealer comprising a hexagonal reel; spaced lugs mounted upon one side of said reel and intermediate the ends thereof and having their adjacent faces cupped; a bar loosely mounted for limited movement between said cupped lugs and arranged in substantially parallel spaced relation to said reel; and means arranged to engage either end of said hexagonal reel to rotate the same and the bar thereon to wind around them and tighten and seal the ends of a flexible band embracing a cargo and having said ends inserted between said reel and bar.

2. A bond tightener and sealer comprising a hexagonal reel; spaced lugs mounted upon one side of said reel and intermediate the ends thereof and having their adjacent faces cupped; a bar loosely mounted for limited movement between said cupped lugs and arranged substantially in parallel spaced relation to said reel; and wrenches arranged to engage either end of said hexagonal reel to rotate the same and bar thereon to wind around then and tighten and seal the ends of a flexible band embracing a cargo and having said ends inserted between said reel and. bar, one of said wrenches having means adjustable to engage said tightened flexible band to prevent a counter rotation of said reel and bar.
